AUTOMOBILE-BUMPER.

To all whom. it mag/cancers:

Ijlp it known that I, RICHARD T. NEWTON, a citizen of the United States of America, and residin in the city, county, and State of New. Yor have-invented certain new and useful Improvements in Automobiie-Biunpors, of which the following is a specification.

My invention relates to automobile biiin ers, and particularly to bumpers for t e rear of a car, the special object of my invention being to provide a combined bumper and spare tire-lock which not only protects the rear of the car and the tire against injury, butalso locks the spare tires or rims against theft or accidental loss.

In the accompanying drawings- Fi re 1 is a plan View of abumper emborlying my invention in one form;

ig. 2 is a rear, elevation thereof;

Fig. 3 is an enlarged side elevation;

Fi 4 is a partial planpf a modified coustruc ion; p

Fig. 51s an enlarged broken plan view of the bumper lock; and

Fi 6 is a plan'of the locklsheath.

ile the bumper may be of any desired type, I have here shown its elements made from fiat's ring steel and coin rising an impact mem er 10 arranged in su istantially horizontal position and stretching across the roar of the car with its ends 11 and 12 curved inwardly toward the car, but laterally extended' to pro'ect to or slightly beyond the wheels l'andJy 14 and their mud guards 15 and 16. Return bends 17 and 18 at the ends of the impact member unitethe latter to the supporting Aarms 19 and 20, which are se curedlto brackets 21 and 22 mounted by means of hook bolts l23 and 24 to the rear ends 25 and 26 `of the chassis side bars. The joint between the supporting armsa19 and and the brackets 21l and 22 is of such nature Athat the im act member 10 may be swung downward` or the reason hereinafter inted out. As here shown, the joint is efected by means of a rivet 27 or bolt 28,

which constitute the axis on which lthe bar is ivoted.

etween the chassis side bars and 26 extends a stienin. rod 22, from which the rear spring 30 1g. 3) 1s hung liv means of a pair of stirrups 31 and 32, and a. cross ving the spring.

the spriif arch 36, the bw of which extends outwardly and -js secured to the mid area.` of the im act member 10 by means of a .bolt 37. he feet 34 and' of this spring 38 and 39, the hook ends of which en age the iiiucr legs of the stil-rups 31 an 32. The bolt 37, which passes through the impact member 10 and the crown of the spring arch 36, has au eye 4t) at its inner end to accommodate the shackle 41 of a'padlock 42, of any suitable type. In order to protect the shackle 41 against cutting, I provide a casing clement 43 centrally apertured at 44 to pass over the shank of the bolt 39 and incase the shackle. This sheath 43 may be made ofjtempered steel or any suitable material which is diiicut to cut.

On many cars it is customary to .support 4arch are pierced by the Ishanlcs of hook bolts at the rear of the chassis spare tires 45 and 46. In `the resent construction I have shown these tires mounted on rims 47 and f supported by a bracket 48 of well known type. The construction of the bumper is such that the impact member 10 extends beyoud the tires with sulicient clearance Vto iprotect thcm from injury,.while the spring arch 36 passes through the circular bracket 48 on which thc tires are mounted and thus cffectually prevents their surreptitious re-4 moral` or their loss should the accidentally fall off the bracket 48. It is o avions that in order to remove a tire -from the bracket 48 it is necessary to open the nullock 42, disengage its shackle 41 from t ic bolt 39, with- `di'awthe holt and swing the impact member- 10 of the bumper down suliiciently to crmit the'lower portion of the tire to he ta en through the space then afforded between the arch 36 andthe impact member 10 in its downwardly swung position.

InA the modification shown in Fig. 4, (one arm 20 of thehnmper being illustrated? Veach arm 20 is'provided with a rearward y extending bar 49 which 'passes through a sleeve 50 forme at the'end of the bracket 22. At the end of the arm 49 a stop pin 51 f )laced undersullicient tension, when pressed inward against the arch 36 and fastened, to v 27 and 28, the

maintain the pivot joints shackle 41, and 'casing 43 (Figs. free from rattle.

Obviously other types of auxiliary s'prin than the arch 3G can be'used with equal e iiciency, and thc shape and curvature of the impact member 10 varied to suit dilerent tastes or conditions without departing from my invention. For example, t e pivot support ma be employed for the arch 36 instead `o for the impact member of the bumV ver, if preferred; the member' may be' simplly a lock bar withoutadding to the resilient strength of the bumper; and other variations will readilyoccur to those skilled in the art. In any event the construction would be such that on impact against the bumper the latter yields suiiieiently to cushion the shock, while at the same time the tires are protected against loss or theft. The particular construction shown is readily and economically manufactured, and the securi means are simple and efficient.
